The sort of exhaust pipe clamp is divided into many types. According to different requirements, we can choose v band clamp, butt joint clamp, lap joint clamp, band clamp, U bolt clamp, Banjo Clamp Clip, etc. When the diameters of the two pipes are the same, V band clamp and butt joint clamp is needed. When the sizes of the two pipes are different, we want to have a good seal and connection, a lap joint Clamp, band clamp or U bolt clamp is a necessity. When the space in the joint of the two pipes is enough. You can use the lap joint clamp to get a good connection, it is a good choice. This exhaust sleeve clamp is ideal for performance exhaust systems, downpipes, cat back exhausts, turbo back exhausts, muffler and more. This type of clamp is a great option if you want a strong clamp that will not distort your exhaust tube. Regular exhaust clamps work fine but when tightened sufficiently to seal they distort the tubes and make it difficult to impossible to separate the tunes in the future. These clamps avoid this issue.
